BLACKHAWK (1952) --- colorized

This is a 15-chapter colorized serial entitled BLACKHAWK. It deals with the Blackhawks, an international team of ace aviators who fought the Axis in World War II, are now battling communist agents and criminals led by the femme fatale, who is using a twin of one of the Blackhawks as a spy. It stars Kirk Alyn, the serials' Superman. Blackhawk is a 1952 American 15-chapter science fiction adventure movie serial from Columbia Pictures, based on the comic book Blackhawk, first published by Quality Comics, but later owned by competitor DC Comics. It was Columbia's forty-ninth serial. The one-sheet poster referred to the serial as The Miraculous Blackhawk: Freedom's Champion.[1] The home video release added the tagline: "Fearless Champion of Freedom".

Blackhawk stars Kirk Alyn as Blackhawk and Carol Forman as the foreign spy that must be stopped from stealing the experimental super-fuel "Element-X"; Alyn and Forman were also the hero and villain of Columbia's earlier Superman.

Blackhawk was produced by the famously cheap Sam Katzman and directed by the team of Spencer Gordon Bennet and Fred F. Sears. It is considered cheap and lackluster, made in the waning years of studio movie serial production.
